Rose passed the YG audition in Australia with the ultra competitive ratio of '400:1' (400 people who audition for every person that passed) prior to her debut. When talking about her audition, Rose had commented, "My dad suggested I audition and I was 100% sure I wasn't going to make it, but I did." She added, "It has been my dream to receive vocal training from Gummy."

The Black Pink member also shared that she wanted to collaborate with IU as well. It appears Rose's wish will finally be fulfilled as she stood on stage with main guest Gummy during the filming for 'Fantastic Duo 2'.
